Hi all,
W3C is organising a workshop on Identity in the Browser, hosted by Mozilla on 24-25/05. Details:
http://www.w3.org/2011/identity-ws/
Whatever comes out of it is likely to have if not a direct impact at least a relationship with what we've been working on here. It also has strong tie-ins to privacy issues. I encourage you to take a look at the CfP and to submit a paper if you think that you have an interest in it.
